Product Link: http://www.novell.com/products/groupwise/ ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a vulnerability in Novell GroupWise, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused by an integer truncation error in NgwiCalVTimeZoneBody::ParseSelf() within gwwww1.dll when GroupWise Internet Agent parses "TZNAME" variables in VCALENDAR data. This can be exploited to cause a heap-based buffer overflow via a specially crafted e-mail containing an overly long "TZNAME" property value. Successful exploitation may allow execution of arbitrary code. ====================================================================== 5) Solution Update to version 8.02 Hot Patch 3. ====================================================================== 6) Time Table 04/03/2011 - Vendor notified. 04/03/2011 - Vendor response. 19/05/2011 - Vendor provides status update. 01/06/2011 - Vendor provides status update. 30/06/2011 - Vendor provides status update. 12/08/2011 - Vendor provides status update. 24/08/2011 - Vendor provides status update. 26/09/2011 - Vendor provides status update. 27/09/2011 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2011-0333 for the vulnerability. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://secunia.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://secunia.com/secunia_research/ Secunia regularly hires new skilled team members.
